DRIVING POSITION MEMORYSYSTEM
A microcomputer will memorize the position of the driver’s
seat, and the positions of the tilt and telescopic steering, and
outside rear view mirrors. Three different driving position
profiles can be entered into the computer’s memory.
Recording a driving position in the computer’s memory can
only be done when the engine switch is selected in “IG −ON”
mode and the selector lever is in the ”P” position.
Setting the driving position
G16068
1. Adjust the driver’s seat, tilt and telescopic steering and
outside rear view mirrors to the desired position.
2. While pushing the ”SET” button, push button ”1”,”2” or
“3” until the signal beeps. The beep sound means that the positions are recorded in the
computer’s memory.
By repeating these two steps
and pressing the remaining
button, the driving position for another driver can be recorded.
To set a new memorized position, select the desired position
and perform step 2. The previous memory will be erased and
the new position will be set.
To make only slight changes to an already memorized position,
the easiest way is to first activate the memorized position, then
make the desired changes and perform step 2 above.
Recalling the memorized position
G16069
When you push button ”1”, ”2” or “3”, the driving position
will be automatically adjusted to the position recorded for
that button.

G17004
Adjust the mirror so that you can just see the side of your
vehicle in the mirror.
Be careful when judging the size or distance of any object seen
in the outside rear view mirror on the passenger’s side
because it is a convex mirror. Any object seen in a convex
mirror will look smaller and farther away than if seen in a normal
flat mirror.
When the inside rear view mirror darkens in ”AUTO” mode, the
outside rear view mirrors also darken to reduce the reflection
of the headlights of the following vehicle. For details, see
”Inside rear view mirror” on page 209.
When you push the rear window and outside rear view mirror
defogger switch, the heater panels in the outside rear view
mirrors will quickly clear the mirror surface. (See “Rear window
and outside rear view mirror defogger switch” on page 56.)
